GSI H2JO! Filter for Water Bottles

Making coffee on trail couldn't be easier! Just fill your bottle with hot water, screw on the filter, add grounds, and close the lid to sit back and let the magic happen. Convert any standard water bottle into an infusion brewing machine. Perfect for hot coffee as well as sun tea. The simple filter keeps the grounds out of your coffee with a minimum of fuss and cleanup.

It also works for making "cowboy coffee" - add the grounds directly to water, then screw on the filter to pour coffee out of the bottle into a mug!
